,WILLIAM J. LU'r'roN, a States, residing at Pat- Passaic and State of M echano a take-up mechanarticularly to that class of take-up mechanisms in which the clothroll is rotated engagement of a disk cloth-roll, with a shaft.

In this class of take-up mechanisms, means are ordinarily provide lating the degree f between the disk, cloth-roll, and the driven gear loose on, said ast on the shaft of the driven gear loose on said through the frictional fast on the shaft of said d for manually regufrictional engagement shaft, and forming the friction driving mechanism of the cloth-roll, t motion ofthe cloth-roll.

The object of my invention is to improve upon the constructio isms of the class an improve ating the cloth roll adapted to be used silk, or like fabrics and in which the rotary motion of the cloth-roll is automatically adreferred to, and d take-up mechanism for opero adjust the rotary n of take up mechanto provide particularly for weaving which is on looms justed, according to the length of the woven fabric passing over the guide-roll from the take-up roll.

In my improvements I provide means for automatically regul ating the friction driving mechanism of the cloth-roll, or the frictional engagement b shaft of the cl loose on said shaft, to adj tion of the cloth-roll of the woven fabric passing over roll from the take-up roll.

invention consist tures of construction of my etween the disk fast on the oth-roll, and the driven gear ust the rotary moaccording to the length the guides iii certain novel feaimprovements,

may be of known construction.

I will now describe my improvements.

S has its journal 8 at each end boss 20 on an arm 20, ed on a stud 21 on the There is a lever 22 which has a hub 22 d on the shaft 7 of the take- 105 from the boss or which has attached a lug 20,

thereto one end of a helically coiled contrac- 23, the other end of said spring 23 in this instance to an extension The spring 23 acts to 8 in engagement with 22 on the lever 22. yieldingly hold the roll the take-up roll 7.

Extending transversely between the levers 22, is a rod 24, which is attached to said levers 22 to cause. them to move together. One end of the rod 24 is extended, see Fig. 1, and has its extreme end 24 reduced, to receive the upper end of a connector or link 25. The lower end of the connector 25 has a rod head 26 adjustably secured thereto, and carrying a pin 263/, which is adapted to enter a hole in any one of the projections or knobs 27 on a wheel 27. The wheel 27 has a screw threaded hub 27 see Fig. 8, which is adapted to rotate on the threaded inner end 28 of a collar 28, loosely mounted on the extended reduced end of the shaft 9 of the cloth-roll 9. The outer end of the collar 28 is secured in a hub 29/ on an arm 29 secured to the. looin frame, see Fig. 1. A helically coiled contraction spring 30 is secured at one end to an extension 22 on each lever 22, and at its other end to a stationary part of the loom frame, and acts to hold the upper end of each lever 22 in its raised position. The wheel 27 bears against a washer 31 loose on the shaft 9, and intermediate the hub of the gear 18 and the hub .of the wheel 27, see Fig. 3. The turning of the wheel 27 on the stationary threaded collar 28, toward the gear 18, Will, through the collar 31, move the gear 18 into closer frictional engagement with the disk 19. The turning of the wheel 27 in the opposite direction will lessen the frictional engagement of the gear 18 with the disk 19. The rotating of the wheel 27, to vary the friction on the driven gear 18 of the cloth-A roll 9, is automatically controlled, through the link 25, lever 22, and the roll 8 journaled in the arms 2O attached to said lever 22.

When there is too much woven fabric com` ing off of the take-up roll, the springs 30 will act to draw down the inner ends of the levers 22, and the downward movement of said levers 22, through the link 25, will rotate the wheel 27, and move it toward the gear 18, to increase the friction between said gear 18, and the disk 19, and cause the cloth-rollv 9 to turn faster to take up the fabric. In case the woven fabric from the take-up roll 7 is shortened, the tension on the fabric is greater and through the roll 8 being drawn down by the fabric 5, the levers 22 at their outer ends are moved downwardly, against the action of the springs 30, and the inner ends are raised, and through link 25, the wheel 27 is rotated and turned away from the gear 18, to lessen its frictional engagement with the disk 19, and allow the cloth-roll 9 to slip, and not to take up the fabric so rapidly. It will thus be seen, that by means of my mechanism, the degree of frictional engagement between the driven gear 18 and the disk 19 fast on the shaft 9 of the takesup roll 9, is automatically ric passing from the take-up roll.

I preferably provide a movable latch 32, see Fig. 2, or other suitable be used to hold the outer ends of the two levers 22 and the roll 8 in their lowered position, against the action of the spring 30, to

l release the friction and allow the goods to be l taken from the cloth-roll by hand, or allow the cloth-roll to be turned in either direction. The latch 32 has in this instance a hub 32', mounted on a stand 33 on one side frame 3, and has an engaging end 32 by which it may be raised and lowered, and a projection 32 to extend over the hub 20 of the arm 20.

It will be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In the take-up mechanism of a loom, a cloth roll, a rotary take-up roll, two pivoted levers, a roll over which take-up roll passes, said roll carried by said levers and movable therewith, means for holding said roll in yielding engagement with said take-up roll, means for yieldingly holding said levers in their raised position and friction driving mechanism for the clothroll, and connections intermediate said levers and said friction driving mechanism, to automatically regulate therotary motion of the cloth-roll, by the raising and lowering of said levers, and the raising and lowering of the roll carried by said levers.
